目前多数铁矿石磁选厂在巩固精矿品位和选矿回收率的同时,都在围绕着节约能源、降低消耗、降低成本和提高经济效益方面进行研究,并采用技术措施。其中重大技术措施之一是增加磁滑轮干选工艺。生产实践证明,采用这种工艺对于铁矿床本身夹层多,混入废石多等条件的矿山经济效果是明显的。 At present, most iron ore magnetic separation plants are concentrating on concentrate grade and beneficiation recovery rate, and at the same time, they are concentrating on energy conservation, consumption reduction, cost reduction and economic benefits, and adopt technical measures. One of the major technical measures is to increase magnetic dry-election process. Production practice has proved that the use of this technology for the iron ore bed itself, mixed with waste rock and other conditions of the economic effect of the mine is obvious.
